目的考察白头翁 Pulsatilla chinensis 荷瘤裸鼠异体移植瘤的抑制作用,并从能量代谢角度探讨其作用机制。方法制备人肝癌Bel-7402裸鼠异体移植瘤模型,通过肿瘤体积、抑瘤率观察白头翁皂苷的体内抗肿瘤活性;生物化学法检测瘤块组织乳酸及ATP的量以观察白头翁皂苷对能量代谢的调节作用;ELISA法检测白头翁皂苷对能量代谢相关酶变化的影响;Western blotting法检测白头翁皂苷对能量代谢调控蛋白缺氧诱导因子-la (HIF-la)的影响。结果白头翁皂苷能较好地抑制肝癌荷瘤裸鼠异体移植瘤的生长,可明显减小肿瘤体积,白头翁皂苷400、200、100 mg/kg抑瘤率依次为42.8%、31.5%、14.9%,呈剂量依赖关系,且对血液白...

Objective: To investigate the antirumour activity of saponins from Pulsatilla chinensis against the Bel-7402 human hepatocellular carcinoma xenograft in nude mice, and to explore the mechanism of energy metabolism. Methods: The antitumor activity in vivo was estimated using a Bel-7402 xenograft model. The tumor volume was measured, the tumor inhibitory rate was calculated, the levels of lactic acid and ATP were assessed in Bel-7402 xenograft in nude mice, energy metabolic enzymes in Bel-7402 xenograft in nude mice were detected by ELISA assay, ...
